- Different varieties of fruits and vegetables have different amounts of nutrients. These differences are important when these products are used to make baby food. We wish to compare the mean carbohydrate content of two varieties of peaches. The data were analyzed with statistical software, and the following output was obtained: N Mean Variety 1 5 Variety 2 7 33.6 25.0 StDev 3.781 10.392 SE Mean 1.691 3.927 Assuming the conditions for inference were met, which of the following is the most appropriate conclusion to draw at the a = 0.05 level?Women are recommended to consume 1700 calories per day. You suspect that the average calorie intake is different for women at your college. The data for the 12 women who participated in the study is shown below: 1808, 1681, 1723, 1847, 1808, 1858, 1461, 1449, 1631, 1635, 1815, 1874 Assuming that the distribution is normal, what can be concluded at the αα = 0.01 level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the population mean is not significantly different from 1700 at αα = 0.01, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is equal to 1700. The data…Women are recommended to consume 1780 calories per day. You suspect that the average calorie intake is larger for women at your college. The data for the 13 women who participated in the study is shown below: 1788, 1802, 1948, 2013, 1684, 1825, 1763, 1678, 2018, 1898, 1828, 1648, 1640 Assuming that the distribution is normal, what can be concluded at the αα = 0.10 level of significance? For this study, we should use (t-test for population mean, z-test for population proportion) The null and alternative hypotheses would be: H0: (symbol) (symbol) ____ H1: (symbol) (symbol) ____ The test statistic (?,z,t) = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is (?, more than, less than or equal to) αα Based on this, we should (accept, reject, fail to reject) the null hypothesis.

- suppose that for x=3, the predicted value is y=6. The data pair (3, 8) is part of the sample data. What is the value of the residual of x=3?Women are recommended to consume 1770 calories per day. You suspect that the average calorie intake is smaller for women at your college. The data for the 13 women who participated in the study is shown below: 1685, 1451, 1931, 1730, 1718, 1814, 1587, 1533, 1823, 1665, 1525, 1882, 1733 Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance?

The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly less than 1770 at αα = 0.05, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is less than 1770. The data…Women are recommended to consume 1820 calories per day. You suspect that the average calorie intake is smaller for women at your college. The data for the 13 women who participated in the study is shown below: 1801, 1544, 1942, 1565, 1828, 1967, 1749, 1900, 1613, 1540, 1721, 1855, 1981 Assuming that the distribution is normal, what can be concluded at the αα = 0.01 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0:H0: ? μ p Select an answer ≠ = < > H1:H1: ? p μ Select an answer ≠ = < > The test statistic ? t z = (please show your answer to 3 decimal places.)
